Ngokwakhiwa kwesitshalo sokuphehla ugesi sikaManuel Moreno Torres emfuleni iGrijalva, imvelo yashintshwa futhi amabhange anesihlabathi asetshenziswa yingwenya yomfula yokwakha isidleke anyamalala, isimo esidale ukuthi ukuzala kancane kwalolu hlobo. E-Tuxtla Gutiérrez, e-Chiapas, i-Miguel Álvarez del Toro Regional Zoo, eyaziwa kangcono njenge-ZOOMAT, yaqala uhlelo ngo-1993 lokuvikela izingwenya ezihlala endaweni yaseSumidero Canyon.
NgoDisemba 1980, ngemuva nje kokuba isitshalo sokuphehla ugesi siqale ukusebenza, indawo engama-30 km ngasemfuleni iGrijalva yamenyezelwa njengeSumidero Canyon National Park. IZOOMAT izazi zebhayoloji zikubone kubalulekile ukuvikela nokuxhasa ukulondolozwa kweCrocodylus acutus ngokwenza izenzo ezahlukahlukene e-situ nase-ex situ, njengokuqoqwa kwamaqanda asendle kanye namachwane, ukuzala ekuthunjweni, ukukhululwa kwezilwane ezakhiwe e-zoo nokuqapha. ukuqhubeka kwezingwenya zalesi siqiwi. Le ndlela yazalwa kanjani iCrocodylus acutus Baby Release Programme eCañón del Sumidero National Park.
Phakathi neminyaka eyishumi yokusebenza, kwenzeke ukuthi kubuyiselwe abasha abangama-300 endaweni yabo yemvelo, ngokuphila okulinganiselwa ukuthi bangu-20%. Kulaba, abangama-235 bazalwa eZOOMAT ngamaqanda aqoqwe epaki futhi afukanywa ngokungeyikho; amaphesenti amancane ayinzalo yezingwenya ezihlala e-zoo noma eziqoqiwe. Ngokubalwa kwabantu nyangazonke eSonyidero canyon, kubhalwe phansi ukuthi izilwane ezinkulu nezindala kakhulu ezikhishwe yizingwenya ezintathu ezineminyaka eyisishiyagalolunye ubudala okuthi ngo-2004 zibe ngabantu abadala, kucatshangwa ukuthi ziyizinsikazi kanti ubude bazo bungaphezu kwamamitha ayi-2.5 .
U-Luis Sigler, umcwaningi ku-zoology futhi ophethe lolu hlelo, ukhombisa ukuthi ngezindlela ezithile zokufukamela bafuna ukukhiqiza abesifazane abaningi kunabesilisa ukuze kukhuthazwe ukwanda kwabantu ngokushesha. Ngezinyanga ezifudumele kakhulu zonyaka, ikakhulukazi ngoMashi, banikezwa umsebenzi wokuthola izidleke futhi baziyise ezikhungweni ze-ZOOMAT; isidleke ngasinye siqukethe amaqanda angama-25 kuye kwangama-50 nesidleke sabesifazane kanye ngonyaka. Intsha ikhululwa ineminyaka emibili ubudala, lapho ifinyelela kubude obungu-35 kuya ku-40 cm. Ngakho-ke, ingane eneminyaka emibili ubudala igcinwa ekuthunjweni ngasikhathi sinye, ngaphezu kwalabo abasenqubeni yokufukamela.
USigler unethemba ngemizamo yokongiwa kwemvelo: “Imiphumela iyakhuthaza, siyaqhubeka nokuthola izilwane ezineminyaka zikhululwa, okukhombisa ukuthi ukusinda isikhathi eside kuhamba kahle. Ekuqapheni kwasemini endaweni yokufunda, ama-80% okubukwa ahambelana nezilwane ezimakiwe, okusho ukuthi inani lezingwenya lenyuke kakhulu, elinenzuzo eqondile yezomnotho emiphakathini ezinikele kwezokuvakasha ngokugibela izikebhe iPaki kaZwelonke ". Kodwa-ke, uxwayisa ngokuthi kuncane okungenziwa uma kungekho sakhiwo sokuqapha esihambisana nezidingo zalesi siqiwi esibalulekile.
ICrocodylus acutus ingesinye sezinhlobo ezintathu zezingwenya ezikhona eMexico futhi esasatshalaliswa kakhulu, kepha kule minyaka engama-50 edlule ukutholakala kwayo ezindaweni zokuphaka zomlando kwehlile. EChiapas njengamanje ihlala ethafeni elisogwini loMfula iGrijalva, enkabeni yedolobha.
